"BIG BIG FAN of SkyVenn!!! Our organization went through a non-profit merger that had a much more customized and larger database (1.9M contacts!) than we did (~40,000). On top of all that, their email platform was expiring within 2 weeks and we needed to make lists and transfer contacts and opt-outs to our email client fast. This is a complicated, time-consuming and detail oriented project that had to be done perfectly to ensure our new, merged organization would have no service interruption in user's email capabilities. SkyVenn performed the transition flawless, painlessly and efficiently. The team are super responsive, thorough and are long-term thinkers to get the most bang for your buck. In short, totally recommended."
